Jenna reads $14$ pages in $28$ minutes.

At this rate, how many pages does she read in $50$ minutes?

Answers

Answer:

I think the answer is 25 pages.

Step-by-step explanation:

14 pages in 28 minutes = 14 pages

7 pages in 14 minutes =7 pages

= 21 pages in 42 minutes = 21 pages

3.5 pages in 7 minutes = 3.5

24.5 page in 49.5 minutes = 24.5 pages

2. Mr. Andrew wants to give each of his students an equal number of the crayons he bought. There are 32 students in Mr. Andrew’s class. How many crayons will each student get?

Estimate first.





Solve the problem and explain your answer using pictures, diagrams, equations, and/or words.




3. How many more boxes of crayons does Mr. Andrew need if he wants each of his students to get 12 crayons? Explain your answer.

Answers

Answer:

Step-by-step explanation:

2.

Because we don't know how many crayons he bought we will call it c.

c = total number of crayons purchased

T = total number of crayons each student gets

To determine how many crayons each student gets we divide c by 32, because that's the number of students in his class.

c / 32 = T

So let's say he purchased 120 crayons.

c = 120

120/32 = T

T = 3.75

Since he can't give a fraction of a crayon, in this case, each student will get 3 crayons.

3.

We will now pretend there are 24 crayons in 1 box.

So T still equals the total number of crayons each student gets and c still equals number of crayons purchased, but now we also have b which equals the number of crayons in 1 box.

c = total number of crayons purchased

T = total number of crayons each student gets

b = number of crayons in 1 box

x = number of boxes purchased

So b*x = c

We can still write the equation:

c / 32 = T

We know T = 12 So we plug 12 in for T

c / 32 = 12  Now multiply each side by 32, so 32 will cancel on the left.

32c/32 = 12 * 32

c = 12 * 32

c = 384

So if he needs to purchase 384 crayons we can use our other equation.

b*x = c    

b = 24

c = 384

So we plug those in.

24x = 384  Divide each side by 24 so 24 will cancel on the left.

24x/24 = 384/24

x = 384/24

x = 16

So he needs to buy 16 boxes of crayons in this instance. We can figure out how many boxes he bought in #2 by using the same equation.

b*x = c  

c = 120 in #2

b =24

24 * x = 120

24x/24 = 120/24

x = 120/24

x = 5

So for each student to have 12 crayons he needs to purchase 11 more boxes (16 - 5 = 11).

This will work for whatever numbers you were given.

Remember:

c = total number of crayons purchased

T = total number of crayons each student gets

b = number of crayons in 1 box

x = number of boxes purchased

b*x = c

c / 32 = T

A data set has a maximum of 200, a minimum of 115, a median of 145, an upper quartile of 150, and a lower quartile of 120. Which statement is true of the box plot of this data set? The box will go from 145 to 150. A line dividing the box will be at 135. The left whisker will go from 115 to 145. The right whisker will go from 150 to 200.

Answers

Answer:

150 to 200

Step-by-step explanation:

IM DORA

The statement that is true of the box plot of this data set is:

"The right whisker will go from 150 to 200."

Option D is the correct answer.

What is the interquartile range?

An interquartile range is a measure of the difference between the upper and lower quartiles of a dataset.

W can find the values of the upper and lower quartile and median from a box plot.

The middle line is the median and the first line is the lower quartile and the last line is the upper quartile.

The formula used is Upper quartile - Lower quartile.

We have,

The box plot of a data set displays the minimum, maximum, median, and quartiles of the data set.

The box represents the middle 50% of the data, with the median marked by a line inside the box.

The whiskers extend from the box to the minimum and maximum values that are not outliers.

Given the information about the data set, we know that:

The median is 145, which means that the line inside the box will be at 145.

The upper quartile is 150, which means that the top of the box will be at 150.

The lower quartile is 120, which means that the bottom of the box will be at 120.

The minimum is 115, which means that the left whisker will go from 115 to the bottom of the box (which is 120).

The maximum is 200, which means that the right whisker will go from 150 (the top of the box) to 200.

Therefore,

The statement that is true of the box plot of this data set is:

"The right whisker will go from 150 to 200."

Answer:

The decrease of the decimal rate -1.05 mm/year can be rounded to -1. You don’t need to round 2.48 because you’re multiplying by -1. Since -1.05 is negative and rounded to a greater value, the estimate could be adjusted to a slightly lesser value, maybe -2.5 or -2.6.

Answer:

The decrease of the decimal rate -1.05 mm/year can be rounded to -1. You don’t need to round 2.48 because you’re multiplying by -1. Since -1.05 is negative and rounded to a greater value, the estimate could be adjusted to a slightly lesser value, maybe -2.5 or -2.6.

Step-by-step explanation:

If you don't want to use that answer this is what they are looking for

Round -1.05 mm/year to –1.

Estimate the total variation as (-1)(2.48) = -2.48 mm.

Because -1.05 is negative and rounded to a greater value, adjust the estimate to -2.5 or -2.6 millimeters

Then, in the middle of the night, he would wake up to transform his living room. It was a small electronics scrapyard, as Kelvin explained. Kelvin was always very interested in technology and inventions, but he lived very poorly. His community did not have modern technology. This did not stop Kelvin. He scrounged through scrapyards and dumps looking for basic components to make his inventions work.The Beginning of ChangeThere was always an important piece missing for his inventions. He needed batteries to power his homemade devices. Kelvin did not have the benefit of a science education at school. Yet, he figured out how to make a battery using soda, metal, and tape.
